Chapter 21: Become One I*
"Why are you looking at us like that, Yu Xiaoling?" Tang Yin asked once Tang Xiao separated their lips, and she also returned to her human form.
"You... you two have gone mad!" Yu Xiaoling shouted at them, her body shaking with anger. "You two are siblings! But you actually have such a disgusting relationship!"
"You're right, we are indeed crazy, especially after everything we've been through since childhood, plus everything that happened seven years ago." Yu Xiaoling was utterly astounded by their madness when Tang Yin pulled out their marriage certificate and showed it to her. "This is our marriage certificate, so we are husband and wife now, and no one will be able to separate us. Perhaps our relationship is disgusting in your eyes, but Xiao'er is my first love, and I am his first love, so we decided to get married."
"You-"
Before Yu Xiaoling had time to scold her, Tang Yin had already stretched out her hand and used her darkness aura to seal her mouth, and she then pulled her to the side of the bed. "Just stand there and open your eyes, and you will be the witness of our union."
"I didn't expect you to be this naughty now, Big Sis." Tang Xiao said as he laid down on the bed, and Tang Yin laid prone in front of his dick.
"Haha." Tang Yin then held Tang Xiao's dick and started jerking it at a steady pace, and her fingers gently stroked its head, causing him to let out a soft moan. "The first time I woke up in that place, I cried for a long time because I thought I had lost you. Even so, I kept missing you in my loneliness, and I didn't even know how much time had passed, which made me stressed and depressed, especially since there was nothing there but darkness, and there was no one to accompany me to talk to."
Tang Xiao let out a heavy sigh after hearing that, and he rubbed Tang Yin's head while gently speaking to her. "It's all right; you don't need to remember that place anymore, and I will continue to accompany you by your side forever."
Tang Yin smiled before sticking out her tongue and licking Tang Xiao's dick up and down, and she kept jerking it while occasionally squeezing it as her other hand gently massaged his sack. Although she had never done it before, she had learned a lot of knowledge about sex from Xiao Ai's system, and she did it in order to satisfy her little brother.
'They are truly insane, especially Tang Yin!' Yu Xiaoling could only curse in her heart, as she couldn't even move a finger, let alone speak. However, her eyes widened as Tang Xiao's dick started to react to his big sister's stimulation, and it quickly towered before her eyes, causing her to gulp hard. 'How... how can he have such a huge dick? Moreover, he is much different from seven years ago; his body is muscular and sturdy now, and his abs look perfect. Ugh! He is my former student, and I shouldn't think about things like that!'
As he enjoyed every bit of the stimulation, Tang Xiao kept looking at Tang Yin with a loving gaze, and his hand gently stroked her head. 'She seems to have learned a lot of things for my sake, or else she wouldn't be this skilled.'
Suddenly, Tang Yin looked up at Tang Xiao and looked at each other, but she inserted the head of his dick into his mouth before nimbly licking it, and her hand continued to pump his hard shaft slowly.
As he did that, Tang Xiao started to let out moans in pleasure, and the small slit above the head of his dick released a small amount of his cum, which Tang Yin immediately licked and swallowed. "Your licking makes me feel so good, Big Sis."
Tang Yin inserted Tang Xiao's dick deeper while she coquettishly winked at him. However, her tongue continued to dance on its head, and by sucking it slightly harder, she gave him even more pleasure. Even her hand pumped his shaft faster, causing him to continue releasing pleasurable moans.
'Damn it! I can't take it anymore.' Tang Xiao held her head and thrust his dick deeper, startling Tang Yin, but she nodded at him before his cum flowed down her throat. "Ugh! I'm cumming, Big Sis."
*Gulp*
Even though she had never swallowed a man's cum before, Tang Yin looked eager to swallow her little brother's cum, and she greedily swallowed every drop of cum that Tang Xiao released in her mouth.
"Hah... Hah..." Tang Xiao gasped for air after finishing his orgasm.
Tang Yin released his dick from her mouth, and she wiped the remaining semen on Tang Xiao's dick before licking it off her fingers. "Hehe, you released so much cum, but I like it, Xiao'er."
Tang Xiao smiled wryly after hearing that. "Sorry, Big Sis. Your suction on my dick was too strong, so I orgasmed too soon."
"It's okay; we still have plenty of time ahead, so we can do it again later." Tang Yin then stretched out her hand to Tang Xiao.
Tang Xiao then pulled and laid Tang Yin on the bed, and he cleansed her mouth with qi before planting a brief kiss on her lips, but he didn't immediately continue his action and admired the beauty of his big sister's naked body.
Actually, Tang Xiao couldn't wait to become one with his big sister, but he didn't want to rush into it and chose to ignite Tang Yin's lust first.
Tang Yin herself also looked at her little brother with a loving but impatient gaze, and she then asked with a tempting smile. "Why do you keep looking at me like that?"
"There's a beauty in front of me, so I have to admire it, right?" Tang Xiao asked back as his fingers trailed along her smooth skin before holding her soft and bouncy breasts, and he began teasing them with gentle massages, causing her body to sway in pleasure.
"Mhn~" As she squeezed the bed sheet, Tang Yin's mouth started to open while releasing a sensual moan from the pleasure that started flowing into her body, especially when Tang Xiao's fingers pressed gently on her sensitive nipples in turn. "Mnh~ We are husband and wife now, so my body and soul belong to you, and you can do whatever you want with me."
Hearing that, Tang Xiao leaned forward and kissed her thick and sweet lips, and he gently nibbled her bottom lips as his hands massaged her breasts slowly and a bit harder, causing Tang Yin to be swept away by even more pleasure.
As she closed her eyes and wrapped her arms around Tang Xiao's neck, Tang Yin returned her little brother's kiss and guided his tongue to enter her mouth, where she gently sucked it.
Tang Xiao stuck his tongue in deeper as he enjoyed his big sister sucking on it, and his fingers started to gently pinch her tiny but hard nipples. Tang Yin immediately spread her legs to the side in response to his sudden ascent onto her, and he tesed her already-damp pussy with his erect dick.
"Mhn~" Sensing that, Tang Yin hugged Tang Xiao's neck tighter, and their kiss became more intense as they enjoyed the sweetness of each other's saliva. Even her body writhed non-stop due to the pleasure that indulged her even more. "Mhn~"
On the other hand, Yu Xiaoling felt her body become hot as she continued to watch them, and her breathing gradually became irregular as her massive breasts moved up and down. Even her legs continued to rub against each other as her love liquid began to wet her pussy and inner thighs. 'Ugh! They're driving me crazy!'
After a while, Tang Xiao slowly worked his way downwards while starting to lick Tang Yin's neck line and leaving a few hickeys there, and he continued to her collarbone before heading towards her cleavage. Both of his hands moved actively by squeezing her breasts a bit rougher, and his fingers repeatedly twirled her nipples.
With her eyes closed and her tongue continuing to lick her own lips, Tang Yin enjoyed every stimulation Tang Xiao gave her, and her body also kept arched upwards. "Mhn~ Xiao'er, please lick my breasts and nipples, and you can wet them with your warm saliva."
Hearing her plea, Tang Xiao's tongue began to move along her breast, and his saliva made her smooth breasts glitter, which made Tang Yin feel warm on her breasts.
After a while, Tang Xiao took Tang Yin's right nipple into his mouth, and his tongue circled it while occasionally nibbling it. Meanwhile, his hand kept playing with her other breast and nipple, and his action brought his big sister deeper into sexual pleasure.
"Mhn~ I've never felt so comfortable in my entire life, and you can play with them more roughly." Tang Yin said that as she moved her hips, it caused their genitals to rub against each other more intensely and her pussy to get even wetter with her love juice that continued to flow out. "Ahh~ That's it; my nipples are getting more sensitive, and your tongue makes me even hornier."
Hearing his big sister's pleasureable moans, Tang Xiao himself became even more aroused, and he stimulated her breasts and nipples even more; he even rubbed his dick more vigorously against her pussy.
"Ahh~ Xiao'er, my mind is becoming increasingly blank, and this pleasure takes me soaring."
Tang Xiao decided to stop stimulating Tang Yin's chest, and he moved downward again while his tongue continued to lick every inch of her smooth body, but he stopped at her abdomen for a while to lick her navel.
"Mhn~ please, move downward; my pussy is waiting for you to stimulate it, Xiao'er."
